General Information
Date Updated: 24 January 2023
Product Design Registration: 202012496
APPLICATION
Circadia is a new premium office luminaire family designed for workplace wellness, productivity and sustainability.
With its dual light component design consisting of a diffuse element and a central array of optical chambers, Circadia provides premium quality, low-glare illumination for the modern workplace.
Delivering a sense of comfort, wellbeing and harmony for occupants with minimal energy consumption, Circadia is the product of choice for asset owners looking to achieve or enhance the WELL, Green Star, NABERS or other sustainability performance rating of their buildings.
The Tuneable White functionality of the DUO variants helps to obtain additional points in WELL V2 under Feature L08 Occupant Control of Lighting Environments.
DESIGN
The DUO2 range offers dual independently controlled Tuneable White light source components (both Ra>=90 across the tuning range).
Made from advanced microstructured film that offers controlled batwing light distribution, Circadia’s diffuse element allows for wider spacing with fewer luminaires required in the lighting array, making it a cost-effective solution for new fitouts and retrofit projects alike.
Diffuse aperture also provides a pleasant transition between ceiling and light source.
The product exceeds BCA 2019/J6 requirements via optimised beam distribution.
OPTICS
White optical chambers with internal diffusers form the primary, task lighting component whilst an independent light source is used to create the diffuse peripheral component.
CONTROL
The optical chambers and the peripheral diffuse component are both Tuneable White, each with its own independent control.
A very wide selection of control and user interface options, based on DALI DT8 and/or CASAMBI wireless, is available.
CIRCADIAN LIGHTING
The combination of LED chips with the right spectral distribution and an optimum beam distribution achieves ideal vertical illuminance levels with high Circadian Stimulus (CS) and Circadian Lighting (Cla) values. Tuneable White functionality provides additional Visual-Biological-Emotional benefits.
LIFETIME
Constant Light Output (CLO) feature comes as standard across the range and ensures no lumen depreciation for the lifetime of the product.
LIGHT QUALITY
CRI90+ (95 typ.) as standard with R9>70 (74 typ.), initial colour consistency better than 3 SDCM as measured separately for cool and warm components.
N.B. COI compliance is only achieved within the 3500-4000K tuning range. This product should not be used as a COI compliant fitting.
